Error: unsupported bitdepth (16) for sprite

[Mia Villaseñor]

Hi! I just tried to build and run your project in Ares (with no modifications), and I got this error:

ASSERTION FAILED: unsupported bitdepth (16) for sprite

I wasn't able to figure out how to change the bitdepth to accommodate that. Any ideas?

I believe there may have been several big changes in Libdragon since I last worked on this, as I see a lot of announcements in the N64Brew discord I haven't caught up on. Could you tell me a bit about the build environment? I'll have to research what exactly changed or find out if it's just a symptom of later libdragon releases.

If it's not the latest, what commit / branch / tag of libdragon are you using? If it was the docker build environment or the prebuilt stable binaries, did it say which version?

[Mia Villaseñor]

That makes sense. This particular machine is running Ubuntu 22.04 with the following compoents/versions that finally got me to a .z64 file (which doesn't work - see screenshot above, but at least it built):

• libdragon@11.0.0 (Commit hash df42e632b6ee05045becd12f49d65573402a822c)
• node v18.4.0
• npm v8.12.1
• Docker 25.0.0
• ares version 134

The first time I ran libdragon init I did get this error (probably because I didn't do a recursive clone and grab the submodule files):

Unable to create submodule. If you have copied the executable in your project folder or you have a file named libdragon, removing it might solve this issue. Original error:

...which I resolved by just deleting the folder and letting init clone it down again with latest (which is how I achieved the version stack mentioned in the beginning):

When I do a fresh recursive clone so that I get the hash you used, it errors out at libdragon init:
